3-Ingredient Oatmeal Cookies Recipe

These simple three-ingredient oatmeal cookies combine ripe mashed bananas, creamy almond or peanut butter, and quick or rolled oats to form a sticky dough that bakes into soft cookies with a tender, chewy texture. Optional ingredients like vanilla extract, salt, or chocolate chips can enhance flavor, but the base recipe remains wholesome and minimal. The cookies maintain their shape on baking and develop lightly golden edges, suitable for a quick homemade treat without added sugar or flour.

Description

The 3-Ingredient Oatmeal Cookies Recipe starts with mashed ripe bananas, which act as both sweetener and binder. Almond or peanut butter adds richness, natural oils, and protein, while oats provide bulk and texture. Mixing these three creates a dough that holds together without spreading during baking, resulting in cookies with a firm yet tender bite.

Baking at 350 degrees Fahrenheit for 10 to 12 minutes softens the oats and sets the dough while lightly browning the edges. Cooling the cookies before removal allows them to firm up and prevents crumbling. Optional additions like vanilla extract or a pinch of salt can round out the flavor, while chocolate chips provide sweet pockets.

This cookie recipe suits a snack or dessert for those seeking few ingredients or a refined-sugar-free option. It requires no added flours or sugars, relying on natural sweetness and wholesome components. The cookies pair well with milk or tea and can be shaped into various sizes as needed.

Ingredients

Servings
  • 3 large banana mashed (1 ½ cups, ripe
  • ½ cup (128g) almond butter or peanut butter
  • 2 cups (200g) quick oats or rolled oats**

Optional Additions:

  • ⅓ to ½ cup chocolate chips
  • 1 tsp vanilla extract
  • 1 pinch salt sea salt

Instructions

  1. Preheat the oven to 350 degrees Fahrenheit and line a large baking sheet with parchment paper (or spray it with cooking oil).
  2. Mash the banana into a mixing bowl until most of the chunks are out (it can be a little chunky just not overly chunky).
  3. Add the peanut butter and oats and mix everything together until a sticky dough forms.
  4. Use a spoon to drop the cookie dough onto the baking sheet, creating any size of cookie you like (note very small cookies will require less bake time). The cookies won’t spread, so form them into the shape you want them to be in - I stick with round mounds.
  5. Bake the cookies for 10 to 12 minutes, or until they are slightly golden-brown around the edges.
  6. Allow the cookies to cool for at least 15 minutes before using a spatula to remove them from the baking sheet to serve.

Notes

  • Use sweetened nut butter for sweeter cookies; choose unsweetened for no refined sugar added.
  • Gluten-free oats can be used for dietary restrictions.
  • Optional mix-ins like chocolate chips or vanilla extract enhance flavor and texture.
  • Form cookies into desired size and shape as they do not spread while baking.
